Quitting an FX2D app (via ESC or cmd-Q) on macOS throws IllegalStateException #4

Open benfry opened 7 years ago

Using ESC to quit an app results in

@benfry I tested it on linux (Linux Mint 18.2 ) and it works fine. 

void setup() {
  size(200, 200, FX2D);
}

void draw() {
}

If I typed ESC the program terminates without error messages.

The same happens here on macOS.

I seem to have fixed that issue on macOS (#5574). Cannot check other architectures, though...

Still need help with a fix for this one… Stack trace from the beta 4 release:
